Question

3. Acetic acid, (CH₃COOH) is the component in vinegar that gives it its acidity. It is a weak acid and only partly ionizes when mixed with water according to the following chemical reaction:

????₃???????? + ??₂?? ? ??₃??+ + ????₃??????^-

Write down the expression for the reaction quotient when acetic acid is mixed with water as shown above.

if at equilibrium the concentration of CH₃COOH is 0.5 M, CH3COO^- is 0.4 M and H⁺ is 1.9 x 10^-5, calculate the equilibrium constant K_a.

5. Consider the following gas phase chemical reaction:

2??(??) ? ??(??)

Write down the expression for the equilibrium constant of this reaction.

If the initial concentration of A is 20 atm pressure, the initial concentration of B is 0 atm and the equilibrium constant K_p for the reaction is .001 atm^-1, calculate the equilibrium concentration of B.

if answering please write legible thanks !!!
